This study proposed an improved double coupling Duffing system adaptive detection method. On this b a s is, the signal is introduced in the dual - coupled Duffing system. Scale processing and adaptive adjustment of the amplitude of the driving force is adopted to achieve the communication room heat environment under the continuity of electromagnetic radiation point infor-mation detection. The experimental results show that the proposed method can effectively suppretromagnetic radiation and ensure the accuracy and completeness of the detection of the electromagnetic radiation point.
